摘要
"5.12"汶川地震对水电工程造成了破坏,位于地震中心区域的映秀湾水电站的震损情况和修复重建设计,是人们关注的重点之一。为全面掌握地震对水电工程的破坏影响,并使映秀湾水电站尽快恢复发电,我院在灾后第一时间对映秀湾水电站展开了全面的灾后调研,在全面了解电站的灾损情况后,对电站首部枢纽进行抗震复核分析计算和灾后恢复重建设计。本文对此进行了介绍。
"5.12" Wenchuan Earthquake damaged the hydropower projects in the area greatly.The damage assessment and the repair design of Yingxiuwan Hydropower Project,located in the central region of "5.12" earthquake,has attracted the attention of the experts and researchers.A comprehensive post-disaster investigation of Yingxiuwan Hydropower Station has been conducted just after the earthquake,to find out the damage of the project and to make preparation for the power generation restoration.Based on the investigation,a seismic analysis and calculation review for the headrace works of the station were carried out.And the repair and reconstruction of Yingxiuwan was designed according to the damage of the earthquake and the analysis results.This paper provides a valuable reference to the seismic and repair design for the similar projects and situation.
